Abstract (en)
The present invention provides a biodegradable article formed from enzyme-synthesized amylose using phosphorylase, wherein the enzyme-synthesized amylose is composed of glucose monomers exclusively bonded by alpha -1,4-glucosidic likage and has a weight average molecular weight of not less than 100 kDa, preferable not less than 600 kDa. The enzyme-synthesized amylose employed in the present invention has a molecular weight distribution (Mw/Mn) of not more than 1.25 and can be chemically modified if desired. The biodegradable article of the present invention can be produced by (a) the enzyme-synthesized amylose and/or its modified one, or a combination of the amylose (a) and another polymer material (b).
